The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, but should not be construed as limiting the present utility model.

[0021] Please refer to Figures 1 to 5 , Figure 1 which is a schematic structural diagram of the overall structure of a high-strength grooving tool of the present utility model, Figure 2 which is a schematic structural diagram of another angle of the overall structure of a high-strength grooving tool of the present utility model, Figure 3 which is a schematic structural diagram of another angle of the overall structure of a high-strength grooving tool of the present utility model, Figure 4 which is a front view of the overall structure of a high-strength grooving tool of the present utility model, Figure 5 which is a top view of the overall structure of a high-strength grooving tool of the present utility model.

[0022] A high-strength grooving tool of the present utility model includes a tool body 101, a left end cutter head 102, a right end cutter head 103, a middle cantilever 104, side strengthening ribs 110 and top strengthening ribs 111; the left end cutter head 102 has a left end inclined surface 106, the right end cutter head 103 has a right end inclined surface 107, the middle cantilever 104 has a groove 105, a locking screw hole 108 and a side chamfer 109. Through the foregoing solution, the problem that in the process of long-term and high-strength use of the existing grooving tool, it often breaks due to insufficient strength of the cantilever structure, affecting normal use, is solved.

[0023] For this specific embodiment, the left end cutter head 102 is fixedly connected to the tool body 101 and is located on the left side of the tool body 101, the right end cutter head 103 is fixedly connected to the tool body 101 and is located on the right side of the tool body 101, the middle cantilever 104 is fixedly connected to the tool body 101 and is located on the side of the tool body 101. The middle cantilever 104 has a plurality of grooves 105, and the plurality of grooves 105 are arranged on one side of the middle cantilever 104. By respectively arranging the left end cutter head 102 and the right end cutter head 103 at both ends of the tool body 101, the normal use of the grooving tool is ensured, and a plurality of grooves 105 are arranged at the position of the middle cantilever 104 on the tool body 101. The grooves 105 on the middle cantilever 104 are intended to reduce the weight of the middle cantilever 104 while maintaining its necessary stiffness and length, and through reasonable design of the grooves 105, the stress concentration of the middle cantilever 104 when stressed can be effectively reduced without sacrificing the middle cantilever 104 and the processing range on the grooving tool, improving the overall strength, thereby solving the problem that in the process of long-term and high-strength use of the existing grooving tool, it often breaks due to insufficient strength of the cantilever structure, affecting normal use.

[0024] Among them, the left end inclined surface 106 is located on the side of the left end cutter head 102. The left end inclined surface 106 is set at the end of the left end cutter head 102 away from the cutter body 101, which improves the strength and durability of the left end cutter head 102, can significantly disperse the stress near the middle cantilever 104, and reduce the risk of fracture caused by local stress concentration.

[0025] Secondly, the right end inclined surface 107 is located on the side of the right end cutter head 103. The right end inclined surface 107 is set at the end of the right end cutter head 103 away from the cutter body 101, which improves the strength and durability of the right end cutter head 103, can significantly disperse the stress near the middle cantilever 104, and reduce the risk of fracture caused by local stress concentration.

[0026] Again, the locking screw hole 108 is located on one side of the middle cantilever 104, and the side chamfer 109 is located on the side of the middle cantilever 104 away from the locking screw hole 108. The staff uses an external connecting piece to screw right into the locking screw hole 108, so that the external connecting piece can be fixed on the groove cutter, and then connected as a whole, which is convenient for subsequent use. The chamfer on the middle cantilever 104 improves the overall connection strength of the groove cutter and extends its service life.

[0027] In addition, the side reinforcement ribs 110 are fixedly connected to the middle cantilever 104 and are located on the side of the middle cantilever 104. The top reinforcement ribs 111 are fixedly connected to the middle cantilever 104 and are located on the top of the middle cantilever 104. The side reinforcement ribs 110 and the top reinforcement ribs 111 cooperate with the side chamfers 109 to improve the overall strength of the middle cantilever 104, thereby making the groove knife stronger and extending its service life.

[0028] A high-strength grooving tool of the utility model ensures the normal use of the grooving tool by respectively arranging the left end cutting head 102 and the right end cutting head 103 at both ends of the tool body 101, and arranges a plurality of grooves 105 at the position of the middle cantilever 104 on the tool body 101. The grooves 105 on the middle cantilever 104 are designed to reduce the weight of the middle cantilever 104 while maintaining its necessary stiffness and length. And through reasonable design of the grooves 105, the stress concentration of the middle cantilever 104 during stress can be effectively reduced without sacrificing the middle cantilever 104 and the processing range on the grooving tool, improving the overall strength. The side reinforcing ribs 110 and the top reinforcing ribs 111 cooperate with the side chamfer 109 to improve the overall strength of the middle cantilever 104, making the grooving tool have higher strength and extending its service life. And by arranging the left end inclined surface 106 and the right end inclined surface 107 on the left end cutting head 102 and the right end cutting head 103, the stress near the middle cantilever 104 can be significantly dispersed, reducing the fracture risk caused by local stress concentration. And the staff screws the external connecting piece into the locking screw hole 108 in the right-handed direction, so that the external connecting piece can be fixed on the grooving tool and then connected into a whole, facilitating subsequent use, thereby solving the problem that the existing grooving tool often breaks due to insufficient strength of the cantilever structure during long-term and high-strength use, affecting the normal use.

[0029] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
